I think fuel capacity for the Wrangler is 19 gallons and the light is supposed to come on with 2 gallons left. My TJ gets that close to empty to turn the light on and I fill it up usually with 14 gallons leaving 5 gallons in there already.

Wrangler gas gauges are notoriously inaccurate, just like Squid said!

Cool thanks for the reply. As long as it holds the 19 I'll make it work. Have some fun in the snow!

For a stretch of time (not sure what years) the 19 gallon tank was an option, but I don't believe they were ever standard. Based on my build sheet from Chrysler I have the larger tank in my '98. I can't remember off the top of my head how much it takes when the light is on, but I know I've pushed it a good many miles and have yet to run dry, knock on wood.

Jeep never made a true 14 gallon tank. They used the 19 gallon tank and just attached a longer fill tube down into the tank. When the fuel level hits the bottom of the fill tube, the pump sees backpressure and shuts off. It can be "upgraded" to a 19 gallon tank by cutting ~3" off the tube.

My 06 TJ unlimited build sheet lists a 19 gallon tank. When the fuel light comes on I usually put about 15 gallons in. At about 13 gallons I reset the hold open switch on the gas pump to its lowest (slow speed) setting otherwise it burps gas all over the quarter panel and the ground.

The base model 2.5 SE were delivered with a 15 gallon (reduced size 19 gallon tank) tank. My 99 and 00 both the same. Based on info here I trimmed my vent tube about 3" to gain the extra capacity when I replaced the fuel pump assembly last year. Keep in mind that the sending unit for a 15 gallon tank is different than the 19. Fuel pump time is a good opportunity to upgrade but you have to order the pump for the 19 gallon tank.

It was a cheap way to rip off consumers by adding this "option" to get a bigger tank. Honestly it still pisses me off! I did the "upgrade" by cutting the vent hose on my "15 gallon" tank. I also replaced entire fuel sender and pump assembly with a 19 gal version. My Jeep goes empty usually at around 14.5 to 15.5 gallons - which means I likely have another 3-4 gallons left. Seems to be par for the course for most owners here.

I have the issue on my 99 TJ It doesn't have the spring loaded license plate gas cover. Just the drivers side screw on cap. I can never get more than 11 gallons in after the light comes on and the needle says empty. This is frustrating and I seem to need to remove the 3 " off the vent tube.

Any instructions for TJ owners?

Run tank down to empty and drop the it. Pull the fuel pump package out and stick your hand in towards the fuel neck and feel around for the vent tube stub that protrudes into the tank. I easily cut off about 3" with a sharp razor knife. Don't forget you will need to upgrade the sending unit to a 19 gallon for a proper read.
